During the 14-day mission, Discovery’s crew will deliver and install the main experiment module and the robotic arm of Japan’s Kibo module. Kibo, which means “Hope” in English, is Japan’s major contribution to the station. The first Japanese component was delivered on the STS-123 shuttle flight in March.

Kibo will be the station’s largest laboratory module, nine feet longer than the U.S. Destiny laboratory and 14 feet longer than the European Space Agency’s Columbus laboratory.

Three spacewalks are planned to help install the Kibo laboratory, work on the station’s cooling system, restore the station to full power-generating capability, and transfer the 50-foot-long heat-shield sensor boom to Discovery.

International Space Station Expedition 17 Commander Sergei Volkov and Flight Engineers Oleg Kononenko and Garrett Reisman are awaiting the arrival of the new module and crew member Chamitoff.

Discovery’s crew will begin a sleep period at 10:02 p.m. and awaken at 6:02 a.m. Sunday to begin its first full day in space. The shuttle is scheduled to dock to the station at 12:54 p.m. Monday.
